[MENTION=559737]Leyland1989[/MENTION] as the guy who added that to the wiki, I should note that's out of date. Or could be. It was several months ago that I went looking through recent flights on FlightAware to figure out where those aircraft were usually flying. Perhaps you or someone else could update it based on more recent info, or confirm it's still current.
